いろいろ買ったが、一番ぴったりくる。コンケイブベアリングに変えたときの回転力ときたら・・・いいです。
All yo-yos have passed the manufacturer's quality inspection. Quality standards vary by manufacturer. Basically, products that can be used normally are within product specifications.
Examples of possible initial defects
- if the following symptoms occur immediately after opening, they may be initial defects:
- (Bind models only) The bearing barely rotates even when flicked with a finger.
- Even after dampening vibrations with a finger during play, the yo-yo vibrates so much that its shape appears distorted.
- Parts that should be installed (bearings, pads) are not installed.
- Examples that do not constitute initial defects
- Package damage
- Color differences from expectations
- Bearing noise or bind model return issues that occur after even a few plays
- Yo-yos that arrived properly assembled but cannot be reassembled after disassembly
- Scratches on the inside of the bearing area, paint chips
- Color variations on the yo-yo that are not noticeable from a distance
- Paint chips that are not noticeable from a distance
- Scratches on the yo-yo that are not noticeable from a distance and barely detectable by touch
- Minor rust on bearing surfaces of models that come pre-strung in the package (minor external rust has almost no impact on performance)
